Colorado officers may demand your name, but silence is not a crime

Section 16-3-103 sits in part 1 of article 3 of title 16 under the catchline "Stopping of suspect." It is Colorado's codification of the investigative detention: the officer needs reasonable suspicion that you are committing, have committed, or are about to commit a crime, and the section closes by saying that the stopping "shall not constitute an arrest." Subsection (2) allows a pat-down for weapons only when the officer, having already stopped you, "reasonably suspects that his personal safety requires it." The operative language has been unchanged since a 2001 amendment at L. 2001, p. 941, § 9.

What the section conspicuously does not carry is a penalty clause. Colorado never enacted a failure-to-identify or refusal-to-identify offense, and a full-text search of the Colorado Revised Statutes for those phrases returns nothing in the criminal code. The gap was then closed from the other direction by C.R.S. § 18-8-104(1.5), added by S.B. 21-271 and effective March 1, 2022: "A person shall not be charged with the offense described in subsection (1) of this section because the person remained silent or because the person stated a verbal opposition to an order by a government official." Obstructing a peace officer under § 18-8-104(1)(a) already required "using or threatening to use violence, force, physical interference, or an obstacle," so words alone never reached it; subsection (1.5) makes that explicit. Obstruction is a class 2 misdemeanor, which since March 1, 2022 carries up to 120 days in jail, a fine of not more than seven hundred fifty dollars, or both, under C.R.S. § 18-1.3-501(1)(a.5).

Giving a false answer is a different matter. C.R.S. § 18-8-111.5, also added by S.B. 21-271, makes it a class 2 misdemeanor to knowingly provide false identifying information to law enforcement authorities, rising to a class 6 felony where the false information results in substantially impeding the investigation or arrest of a person for a felony crime as defined in § 24-4.1-302(1). The statute defines "identifying information" narrowly: a person's name, address, birth date, social security number, or driver's license or Colorado identification number.

Drivers are the one group Colorado does compel. C.R.S. § 42-2-115 says a licensed driver who has the license, instruction permit, or identification card in immediate possession may not refuse to remove it from a billfold, purse, cover, or other container and hand it to an officer who reasonably suspects a violation of articles 2, 3, 4, 5, 6, 7, or 8 of title 42. Violation is a class A traffic infraction. Note the two limits built into it: the duty attaches only to a document you actually have with you, and only where the officer suspects a title 42 vehicle offense. For suspected impaired driving, C.R.S. § 42-4-1302 mirrors § 16-3-103 and lets an officer require name, address, and an explanation, without mentioning identification at all.

The duty to identify also runs the other way in Colorado. Under C.R.S. § 24-31-309(4)(a), a certified peace officer must hand over a business card, without being asked, to any person detained in a traffic stop but not cited or arrested, carrying the officer's name, division, precinct, and badge or other identification number, a telephone number for comments, and information on how to file a complaint. Undercover operations are exempt. Subsection (3.5) of the same section, added by S.B. 20-217, requires an officer to have a legal basis for making any contact with a member of the public, consensual or not, and to report the reason for the contact, its duration, and its result to the employing agency.

5) bars a Colorado prosecutor from charging obstruction because a person remained silent or voiced opposition to an order. 5, a class 2 misdemeanor punishable by up to 120 days in jail and a fine of up to seven hundred fifty dollars, or a class 6 felony where the lie substantially impedes a felony investigation or arrest; obstructing a peace officer under § 18-8-104, also a class 2 misdemeanor, which requires violence, force, physical interference, or an obstacle; and, for drivers, a class A traffic infraction under § 42-2-115 for refusing to hand over a license in immediate possession.

Complaints about how a stop was conducted go to the employing agency through the business card the officer must supply under § 24-31-309(4)(a), and each agency must compile and publish the profiling allegations that come in that way, without naming officers or complainants, under § 24-31-309(4)(c).
